We need to decide on a versioning scheme for release open solo to the masses. It's important, and it ensure the controller and solo are operating the same compatible versions. It also will distinguish between people's custom tinkering, and real tested releases.
We also unfortunately need to distinguish between releases for the stock solo and Solo's with the Green Cube running master. The only difference between the two would be the ArduCopter version it contains. The old ArduCopter-Solo for the stock cubes and ArduCopter 3.5.x for the green cubes. The rest of the FW for the IMX and artoo is the same.
The last 3DR complete release was 2.4.2
Suggestions:
I think we should start our own versioning with 1.0.0 rather than continuing where 3DR left off. That will avoid any and all ambiguity.
To distinguish between stock solos and green cube solos, I suggest appending the color to the version name
Our first release would look like Open Solo v1.0.0 Green for the green cube solos. It would contain ArduCopter 3.5.2. Then Open Solo v1.0.0 Black would be for the stock solos and contain the old ArduCopter-Solo version.
